Enhancing Performance in Mixed‐Criticality Real‐Time Systems Through Learner‐Based Resource Management

open access: yesIET Cyber-Physical Systems: Theory &Applications, Volume 10, Issue 1, January/December 2025.
The research addresses the critical challenge of resource management in mixed‐criticality (MC) systems, which integrate tasks with varying criticality levels onto a shared platform. The authors propose a novel learner‐based approach that effectively predicts system mode transitions and optimises resource allocation, leading to significant improvements ...

A Systematic Literature Review on Application of Agile Software Development Process Models for the Development of Safety‐Critical Systems in Multiple Domains

open access: yesIET Software, Volume 2025, Issue 1, 2025.
This paper presents a literature review on using agile for safety‐critical systems (SCSs). We have systematically selected and evaluated relevant literature to find out major areas of concern for adapting agile in the development of SCSs. In the paper, we have listed the most used Agile process models and reasons for their suitability for SCS, then we ...

Joint safety and security risk analysis in industrial cyber‐physical systems: A survey

open access: yesIET Cyber-Physical Systems: Theory &Applications, Volume 9, Issue 4, Page 334-349, December 2024.
There is a dearth of literature reviews encapsulating recent advancements in safety and security (S&S) joint risk analysis for industrial Cyber‐Physical Systems, which provides the motivation for this study. The authors review the methodologies in this field, delve into the S&S relationships involved, and propose 12 criteria for evaluating these ...
